Hosting React + .NET 8 API on IIS

To serve your React app at www.example.com and a .NET 8 Web API under www.example.com/api, publish the API into its own folder and configure IIS with Add Application.

# 1. Publish your API
dotnet publish -c Release -o .\publish

# 2. Copy folders to server
D:\Sites\MySite\react-build   (React build output)
D:\Sites\MySite\api           (Web API publish output)

# 3. IIS setup
- Root site → points to react-build
- Add Application → Alias: api → Physical path: D:\Sites\MySite\api
- Assign a dedicated App Pool (No Managed Code)

# 4. SPA rewrite rule (exclude /api)
<rule name="SPA" stopProcessing="true">
  <match url=".*" />
  <conditions logicalGrouping="MatchAll">
    <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
    <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
    <add input="{REQUEST_URI}" pattern="^/api($|/)" negate="true" />
  </conditions>
  <action type="Rewrite" url="/index.html" />
</rule>

# 5. Test
https://www.example.com/api/health

Keep the API and React app in separate subfolders under the same site root. This keeps deployments clean and avoids routing conflicts.
